3β-HYDROXY-5α-ANDROSTAN-17-ONE (Epi-Androsterone) is the 3β-isomer of Androsterone and is commonly detectable in sweat, saliva and urine of both male and females. Epi-Rone as it is commonly referred to has the ability to tone down the alpha dominance typically associated with Androsterone.

When used in conjunction with other alpha-dominant eliciting pheromones, Epi-Androsterone can act as a ramp-up or bridge to the effect. In many instances Androsterone or other dominance molecules can project the wearer as arrogant or stand-offish. This is associated with a signature that is difficult to believe by those effected that the wearer is deserving of such status and therefore can appear as not-worthy of respect.

It is a common misconception that an alpha-dominant pheromone blend is a respect blend when it is more a fear reaction. Those effected are fearful of reprisals from the alpha-dominance signature and therefore likely to complete the task if presented by a colleague or boss. However at the same time they are less likely to engage in actual dialogue or communication beyond what is required. Nor do they respect or feel trusting of the person.

It is in these types of situations that the incredible benefits of Epi-Androsterone are evident. By creating a ramp-up or bridge you are building a mutual respect and trust between the wearer and those effected. It is through this chemosignal agreement that people will want to engage and communicate and when asked to do something, again in a working environment, will happily go about the task. When people feel appreciated and that respect is reciprocated, even if only through appearance, the dominance effect becomes the agreement effect.

When paired with the other beta isomer of Androsterone, Etiocholanolone (5β-isomer) the wearer can create a sense of trust and well being, with calming confidence. It has been reported many times that confidence is the single most attractive trait that is sought out in others for dating and sexual purposes. Epi-Androsterone either by itself or when paired with another great beta isomer or simply Androsterone is a must have for every real pheromone enthusiast and hobbyist. A unisexy pheromone molecule you need to have.

Our DiscoverXS community researchers have reported awesome results anywhere from 2.5 mcg on the low end all the way to 50 mcg and above on the higher scale. We recommend a dosage of about 10-20 mcg per spray to begin with incrimental increases from there.

This paper reviews state-of-the-art knowledge on steroid biosynthesis pathways in the pig and provides an updated characterization of the porcine genes involved in these pathways with particular focus on androgens, estrogens, and 16-androstenes. At least 21 different enzymes appear to be involved in these pathways in porcine tissues together with at least five cofactors. Until now, data on several porcine genes were scarce or confusing. We characterized the complete genomic and transcript sequences of the single porcine CYP11B gene. We analyzed the porcine AKR1 gene cluster and identified four AKR1C, one AKR1C like genes and one AKR1E2 gene. We provide evidence that porcine AKR1C genes are not orthologous to human AKR1C. A new nomenclature is thus needed for this gene family in the pig. Thirty-two genes are now described: transcript (30+2 characterized in this study) and genomic (complete: 18+1 and partial: 12+1) sequences are identified. However, despite increasing knowledge on steroid metabolism in the pig, there is still no explanation of why porcine testes can produce androstenone and epiandrosterone, but not dihydrotestosterone (DHT), which is also a reduced steroid.

Non-steroidal drugs that increase endogenous testosterone (T) may be used to exploit ergogenic effects of androgens in power sports. While superactive GnRH analog use is suspected, neither screening nor detection tests are developed. This study aimed to determine if (a) stimulation for 5 days by leuprolide (a superactive GnRH analog) of serum and urine steroids and urine LH is reproducible at a 2 week interval, (b) nandrolone decanoate (ND) co-administration masks responses to leuprolide administration, (c) performance of urine measurement of leuprolide and M1, its major metabolite, as a detection test. Healthy men were randomized into a 4 week parallel group, open label clinical study in which all men had daily sc injections of leuprolide (1mg) for 4 days in the 1st and 3rd weeks with hormone-free 2nd and 4th weeks. In the 3rd week, men were randomized to either ND injections or no extra treatment. Serum steroids were determined by liquid chromatography, tandem mass spectrometry (LC-MS), urine steroids by gas chromatography, mass spectrometry (GC-MS), urine leuprolide and M1 by high resolution LC-MS and urine LH by immunoassay. Leuprolide stimulated striking, reproducible increases in serum and urine LH and steroids (serum T, dihydroT (DHT), 3α diol; urine T, epitestosterone (E) and androsterone (A). ND suppressed basal serum T, E2, 3α diol, and urinary E but did not mask or change the magnitude of responses to leuprolide. Urine leuprolide and M1 measurement had 100% sensitivity and specificity in detecting leuprolide administration up to one day after cessation of injections with the detection window between 1 and 3 days after last dose. Screening using urine steroid and LH measurements, optimally by urinary log10(LHxT), correctly classified 82% of urine samples. It is concluded that leuprolide stimulation of endogenous testosterone is reproducible after a 10-day interval, is not masked by ND and is reliably detected by urine leuprolide or M1 measurement for at least 1 day after administration.

Musk is widely used as a traditional drug in Asia for the treatment of stroke, tumour, and cardiopathy with an oral dosage of 0.03-0.1 g per day. Because of the potential anabolic effect, musk preparations have been included in the list of medical products containing prohibited substances employed for doping. The application of musk pod formulation was regarded as the reason of some adverse analytical findings in the 2011 FIFA Women's World Cup. In order to investigate the influence of musk administration on the doping test, we executed a chemical analysis and excretion study. The gas chromatography/mass spectrometry (GC-MS) analysis demonstrated the diversity of steroid concentrations in musk samples. Furthermore, the δ(13)C-values of steroids from wild deer musk showed more depleted than those of domestic deer musk by gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS) analysis. Because the steroids from some musk had δ(13)C-values in the range of naturally produced steroids in human body, the possible abuse of this kind of musk is very hard to be detected by isotope ratio mass spectrometry (IRMS) in doping control. Musk grains from wild and domestic deer were administrated for the excretion study respectively. Spot urine samples were collected from two male volunteers before and after 100 mg musk grains administration. The profiles and carbon isotope ratios of urinary steroids were determined by GC-MS and GC/C/IRMS. The ingestion of either wild or domestic deer musk did not lead to the adverse analytical finding of doping control in the single dosage of 100mg.

Dehydroepiandrosterone (DHEA) is a multifunctional steroid with a broad range of biological effects in humans and animals. DHEA can be converted to multiple oxygenated metabolites in the brain and peripheral tissues. The mechanisms by which DHEA exerts its effects are not well understood. However, evidence that the effects of DHEA are mediated by its oxygenated metabolites has accumulated. This paper will review the panel of oxygenated DHEA metabolites (7, 16 and 17-hydroxylated derivatives) including a number of 5α-androstane derivatives, such as epiandrosterone (EpiA) metabolites. The most important aspects of the oxidative metabolism of DHEA in the liver, intestine and brain are described. Then, this article reviews the reported biological effects of oxygenated DHEA metabolites from recent findings with a specific focus on cancer, inflammatory and immune processes, osteoporosis, thermogenesis, adipogenesis, the cardiovascular system, the brain and the estrogen and androgen receptors.

5β-ANDROSTAN-3α-OL-17-ONE (Epi-Androsterone) is a pheromone molecule detectable in the sweat, saliva and urine of both men and women and therefore unisexy. The beta-isomer of Androsterone your signature will be recognized as respectful, trustworthy and honorable. This molecule is ideal for pairing with socially dominant molecules and can bridge the gap most commonly associate as arrogance or obtuse if the signature is not understood or believable. Great for both men and women.
